FORCE-JET DEVICE FOR CLEANING QUARRY-HOLES, 8w.

SPECIFICATION forming part of Letters Patent No. 666,799, dated January29, 1901.

Application filed November 1, 1900. Serial No. 35,089. (No model.)

To all whonz it may concern:

Be it known that we, SAMUEL W. BUCK- WALTER and HEBER F. BUCKWALTER,citizens of the United States of America, and residents of Reading, inthe county of Berks and State of Pennsylvania, have invented certain newand useful Improvements in Force-Jet Devices for Cleaning Quarry-Holes,&c., of which the following is a specification.

Our invention relates more particularly'to apparatus for convenientlyraising either semi solid or liquid matter from drilled quarryholes orthe like by utilizing the steam or compressed air ordinarily employed todrive the drill in the form of a force-jet; audit consists in the novelconstruction of the nozzle, by means of which said jet is effectivelyemployed for the purpose.

The invention is fully described in connection with the accompanyingdrawings, and is specifically pointed out in the claims.

Figure 1 represents our improved device as applied to a drilled hole inrock for the purpose of cleaning the same. Figs. 2 and 3 arerespectively a sectional elevation and plan view of our improvedforce-jet nozzle.

a represents a rock-drill hole from which the drill has been removed andour force-jet nozzle B, with its connected supply-pipe P, introduced toclean out the same preparatory to further drilling or to charging thehole. The pipe P of course is provided with a suitable valve to controlthe supply of steam or compressed air, as the case may be. The cleaningoperation consists merely in lowering the nozzle until its lower end,which is preferably provided with a series of supporting-feet g, touchesthe bottom and then turning on the jet and raising the supply-pipe andnozzle, the dirt, 850., in the hole being forced out in advance of thelatter, as hereinafter described. A flexible hose connection to thesupply-pipe is employed to permit of convenient manipulation.

The force-jet device 13 is a single piece, preferably of cast-brass. Itis formed with a cylindrical shank or body portion 5, screwthreaded forattaching it to the pipe P, and a conical tip portion 0 of largerdiameter at the top than the body I) and provided with an inner chamberd, in communication with the supply-pipe through the body I), and with acircular series of outlets c, opening upwardly therefrom around saidbody b and inclined outward, so as to direct the circle of dischargingsteam or air-jets against the wall of the hole or bore a. In addition tothese upwardly-discharging outlets from the chamber 01 we provide forcleaning purposes a bottom outlet f, the mouth of which is prefer-- ablysupported somewhat above the bottom of the hole a by means of feet g, asalready stated, so as to prevent possible clogging of the outlets by thedirt naturally collected at the bottom of the hole. To insurecommunication between the bottom outlet f, with sufficient space for theraising of the dirt at the bottom of the hole, the outer wall of the tip0 is provided with longitudinal grooves h, opening above between theoutlets e, as indicated in Fig. 3.

Having introduced the device as indicated in Fig. 1 and turned on thesteam or com pressed air the latter will be discharged upwardly throughthe circular series of outlets e and downwardly through the outlet f.The effect of this bottom discharge is to thoroughly loosen and displaceany removable matter below the nozzle B, which matter will be raisedupward around the grooved walls of the device and come under the directaction of the circular series of jets from the outlets e and be carriedout by the latter, together with any matter adhering to the walls of thehole above the nozzle as the latter is raised. To prevent unduescattering of the ejected matter and escaping steam or air, wepreferably employ a guard 10 at the top of the hole through which thepipe P loosely passes.

By means of our improved device every particle of dirt may be quicklyand easily removed from the hole and the walls and bottom left clean anddry for immediate charging of the hole. Furthermore, the device may Joevery satisfactorily used for raising water or other liquid from drivenpipes, the bottom outlet f being dispensed with, if desired.

What we claim is 1. A force-jet nozzle for cleaning quarryholes, &c.,havinga shank or body adapted to be connected to a pressure-supply pipe,and

a chambered tip below said connection hava central bottom outlet, andsaid tip having inga circular series of dischargeoutletsopenexteriorlongitudinal grooves between said ing upwardly around said shank orbody, outlets, substantially as set forth.

said tip having exterior longitudinal grooves Signed at Reading,Pennsylvania, this 26th is 5 bet-ween said outlets substantially as setforth. day of October, 1900.
